The WHO reiterated Friday there was “no adequate data” on switching Covid-19 vaccines between doses after France said under-55s who received an AstraZeneca first jab should get their second from a different vaccine.
The World Health Organization has called for studies on so-called mixing and matching between vaccines but said there was no comprehensive data so far on which it could make any recommendations.
The UN health agency, therefore, recommends that the same product should be used for both doses.
In February, the WHO’s Strategic Advisory Group of Experts on Immunization (SAGE) issued its recommendations on how the AstraZeneca-Oxford vaccine should be used, WHO spokeswoman Margaret Harris told reporters.
“There is not adequate data to be able to say whether this is something that could be done,” she said.
“So they were recommending that at this stage, interchangeability of vaccines was not something that we could give a recommendation on.
“But they did make a research recommendation that this is studied so that we could understand whether or not it was a strategy that could be used.” – AFP
